In a model with private information of the worker about her ability and unobservable effort choice, the role of public and private employment services is analyzed. The coexistence of an inefficient employment exchange and an efficient private agency may lead to optimal screening with first best...

With the help of a simple model, we show that the hindsight bias can lead to inefficient delegation decisions. This prediction is tested experimentally. In an online experiment that was conducted during the FIFA World Cup 2010 participants were asked to predict a number of outcomes of the...

We investigate violations of consequentialism in the form of the stochastic dominance property. The property is shared by many theories of choice and implies that the decision-maker prefers receiving the best outcome for sure over all lotteries that involve multiple outcomes. We run experiments...

When applying to a university, students and their parents devote considerable time acquiring information about university programs in order to form preferences. We explore ways to reduce wasteful information acquisition, that is, to help students avoid acquiring information about out-of-reach...

Die Dissertation enthält drei Aufsätze, welche sich mit Prinzipal-Agenten Beziehungen in Verbindung mit moralischem Risiko beschäftigen. Dabei ist der Agent für die Ausführung von multiplen Aufgaben (Multitasking) verantwortlich. In dem ersten Aufsatz wird ein Prinzipal-Agenten Modell...

Die Dissertation besteht aus drei Kapiteln. Im ersten Kapitel wird unter der Bezeichnung “Adjustment Utility” eine neue Komponente individuellen Nutzens eingeführt. Mit einem Experiment, daß ich mit Studenten durchgeführt habe, zeige ich erst, daß diese Nutzenkomponente existiert. Dann...

We perform an experiment where subjects pay for the right to participate in a shareholder vote. We find that experimental subjects are willing to pay a significant premium for the voting right even though there should be no such premium in our setup under full rationality. Private benefits from...

In order to address the impact of regulation on ethical concerns of consumers, we study the effect of a minimum wage. In our experimental market, consumers have monopsony power, firms engage in Bertrand competition, and workers are passive recipients of a wage payment. Two treatments are...

We study beliefs and choices in a repeated normal-form game. In addition to a baseline treatment with common knowledge of the game structure and feedback about choices in the previous period, we run treatments (i) without feedback about previous play, (ii) with no information about the...

We investigate the matching algorithm used by the German central clearinghouse for university admissions (ZVS) in medicine and related subjects. This mechanism consists of three procedures based on final grades from school (Abiturbestenverfahren, Auswahlverfahren der Hochschulen) and on waiting...
